Well you certainly got my attention with your video. Sounds great.
I have had corsa sports and kooks headers for over a year now and although I like the sound most of the time, the popping on decel really bothered the wife and at times, me. So I just reinstalled the stock mufflers last week. It is just too quiet. I was seriously thinking about an NPP setup with the m2w switch. Looks like this post is a good place to start. Are the mufflers stock? Is there any drone? Any advice would be helpful. thanks.

Here is kooks headers, NPP and my NPP in a box controler
I been sayin' this since the day I put 'em on! With the exception of the collective mods that laid down 450rwhp, this is the coolest mod I've done. Guys, whether you go big & mod your cars to make lotsa power in any manner or just add headers & NPPs this is the way to go!

Closed your gonna be close if not same as stock you're running now, no drone, no popping during decel. Open under normal just much deeper & louder w/ some drone & popping under high rpm decel. At WOT as loud as they come in an AWESOME way! Yes they are stock GM option from '08 & standard on all Z06s. The NPPs are 2.5" & will bolt on to what you have, Z06s are 3" & will require mod & have sound slightly deeper, the NPPs tend to have a higher/louder pitch at WOT too. Oddly enough they changed them for '09 C6s, so you'll need '08s for direct bolt on. The way to go is get a set of used NPPs off an '08 (I lucked out & got a set of brand new takeoffs cheap) from $500 (dirt cheap) to $1000 (way high) but new even more. Get controller from either vendor posted whos options cover your needs, realistically the simplest is the best on/off vacuum from engine, but all are a snap to install. If you have any questions you're welcome to send PM. I guarentee you will be pleased with outcome of adding these.
